They might be putting it in this size of a container so that it would fit properly in a D size receptacle. I use rechargable batteries, and I wouldn’t be suprised to find that if I opened up my rechargable AA’s, they wouldnt fit into my xbox controller anymore, and I wouldnt assume it’s because they want me to buy more disposable batteries. They probably have that somewhere in their mission statement, they are all corporations chasing profits, that’s what companies do. What about those disposable batteries sony gives you with blu ray players? They’re disposable and they last a short amount of time. It’s hypothetical but I would never buy a pair of batteries by Sony.

Perhaps Energizer should put some thoughts into creating a new AA to D size adapter as seen from the picture, Energizer sure can do a better job than other vendors at this.

Searching online, cost of Energizer AA 2450mAh is ~USD 3.50 a cell, while Energizer D is ~USD 4.10 a cell, that means the adapter is ~USD 0.60, which is about 2.5 times less than the price of what others are selling (~USD 1.50/pc).

As your “research indicates that the high upfront cost for high capacity rechargeable batteries and special charger would discourage many users from trying these batteries”, having a 60 cents adapter will surely benefit these users and who knows, it may drive your sale of those AA cells up…

So, in the name of benefiting the users, perhaps you can take down the production line of these low capacity potentially deceiving minimal market less cost effective D-sized 2500 mAh cell and charger and start planning for a new AA to D (and maybe C) cell adapter? …

All Energizer NiMH batteries have the mAh capacity rating on the label. There is no deception concerning the battery capacity and the D size designation only represents the batteries physical dimensions. We have found that most D size devices will work satisfactorily with the Energizer NiMH batteries and the rechargeability of the product is the true advantage of this chemistry.

D size rechargeable batteries have historically used a smaller internal unit cell. The main driving force behind this design is to keep the battery affordable to the average consumer. High capacity rechargeable batteries are more expensive than our standard rechargeable D size battery due to the increased volume of materials needed. In addition, they require a higher capacity charger to deliver acceptable recharging times which are also more expensive. Our research indicates that the high upfront cost for high capacity rechargeable batteries and special charger would discourage many users from trying these batteries.

Clearly a high capacity D size NiMH battery would be beneficial in certain applications but we have found that the market for this type of battery is minimal due to overall cost. Energizer will continue to evaluate this market and look for a cost effective opportunity for higher capacity NiMH batteries.

As for deception, as I said in the article the issue is not so much what Energizer describe their battery as, but how consumers may not recognise the differences between the rechargeable D and a standard D-sized disposible, the latter of which can offer much more than 2,500mAh. Not only that, but other manufacturers offer D-sized rechargeables that don’t wrap a smaller cell in a dummy case, and obviously offer more mAh than this Energizer D.

Whether we need more customer information so that buyers know what they’re looking at when mAh is listed on a battery, or manufacturers charging more reasonable amounts for halfway measures like this Energizer, I don’t know. What do you think?

Thu, 27 Aug 2009 12:01:06 +0000http://www.slashgear.com/?p=53991#comment-59635Here’s the facts. The Energizer D is a consumer (retail) version rechargable D which has in the past by all manufacturers (Duracell, Rayovac, Radio Shack) been a dummy case with a smaller cell (normally a sub-C cell).

The Energizer D does not have a AA inside it is in fact a production size sub-C cell. It is not deceiving in that it plainly lists the capacity on the label.
